Applications of 358-23-6
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a potent acylating agent for synthesizing intermediates of antibiotics, antiviral agents, and cardiovascular drugs | Reacted with alcohols or phenols under low-temperature, inert conditions to generate trifluoromethanesulfonates |
| Organic Synthesis | Facilitates key carbon–carbon bond-forming reactions, including Diels–Alder and Friedel–Crafts reactions | Employed as a Lewis acid catalyst; requires strict control of moisture and reaction temperature (typically −20 °C to ambient) |
| Electronic Chemicals | Key raw material for producing lithium-ion battery electrolyte components (e.g., LiTFSI) | Converted to final product via sulfamic acid reaction followed by lithiation |
| Pesticides | Introduces the trifluoromethanesulfonyl functional group during synthesis of high-efficacy insecticides and herbicides | Introduces the trifluoromethanesulfonyl group into molecular frameworks via nucleophilic substitution |
| Materials Science | Monomer for synthesizing high-temperature-resistant polymers (e.g., poly(trifluoromethanesulfonate)) | Undergoes condensation polymerization with bisphenol compounds |
| Analytical Chemistry | Used as a volatile ion-pairing reagent in mass spectrometry | Forms charged complexes with analytes to enhance mass spectrometric detection sensitivity |
